selftests: forwarding: lib: Extract trap_{, un}install()

Browse source 
A mirror-to-vlan test that's coming next needs to install the trap
unconditionally. Therefore extract from slow_path_trap_{,un}install()
a more generic functions trap_install() and trap_uninstall(), and covert
the former two to conditional wrappers around these.
